Replacement magnetic holders for Neptune optical sensors OS-1

[Jboulerice]

I got myself in a jam where I decided I didn’t want to introduce leaks into my salt fill and waste containers for my auto water change system but ordered two optical sensors without the holders.

Called BRS, they don’t sell them individually... called Neptune... they don’t sell them either...

Turns out they must buy these wholesale but it’s pretty much a exact replacement...

This would be a pretty easy diy if you wanted to do it that way.

Order some neodymium magnets a small sheet of acrylic, epoxy to coat the magnets, and some adhesive.

Cut to size, Drill out the hole for the probe, heat bend the acrylic, dip the magnets, glue them on after curing.

For that price it was much easier to get the product I recommended, they arrived tonight so I’ll be posting pictures soon, it’s an easy fix vs the DIY way would end up being more of an expense in the start up.

They do sell sealed magnets already priced at 14$ plus shipping from another thread I looked into:

And exactly what Neptune is using:

Neptunes on the right^
And they definitely are using the same supplier... honestly save yourself the money on OS-1’s and just buy them without the holder; you’ll get more stupid adapters you can use for other things!

Here’s my usage; high and low sensor on my salt reservoir and a high sensor for my waste reservoir in my auto water change system.. no more worries about leaking through the drilled holes and also no ruined containers...

Note: the pointy part of the sensor should NOT be pointed down. As the liquid level drops past it, a drop can form on it and mess up any trigger points.

Yeah they are pretty clear to point up or sideways, luckily my containers are easy to reach in....
